The sternal angleis the least likely part of A. the sternum to fracture in the elderly. B. occurs at the sternoclavicular joint.
Bumek [7]

Sternal angle marks the joint between the sternum and the 2nd rib.

Option E.

<h3><u>Explanation:</u></h3>

Sternum is the breast bone which is a dorsi ventrally flattened bone present in thorax of human. It gives the support for the ribs where the ribs join. A sternum has three parts - Manubrium sterni, body of sternum and the xyphoid process.

The sternum has attachments of a total of 10 ribs and clavicle. The clavicle and the first rib joins in the Manubrium sterni, and the 3rd to 10th rib joins in the body of sternum. The 2nd rib joins in a facet which is partly in Manubrium sterni and partly in body of sternum. This place id also called the sternal angle. So the sternal angle marks the joint of 2nd rib to sternum.

leonid [27]

Answer:

1. Mitochondria

2. Chloroplast

3. the formation of eukaryotic cells

4. DNA

Explanation:

The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.

The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.

The evidence which supports their ar:

1. The same size of the organelles to the bacteria

2. The presence of the circular DNA of the organelles like bacteria  

3. The similarity in the 30s and 70s ribosomal subunits.

Chromosomes become visible, crossing-over occurs, the nucleolus disappears, the meiotic spindle forms, and the nuclear envelope disappears.
In metaphase 1:
The pairs of chromosomes (bivalents) become arranged on the metaphase plate and are attached to the now fully formed meiotic spindle. The centrioles are at opposite poles of the cell.
